The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

In the description of the present application, it is to be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the present application and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular manner, and are not to be considered limiting of the present application.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

In this application, unless expressly stated or limited otherwise, the terms "mounted," "assembled," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integral; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as the case may be.

The filter is a frequency selection device, and a connector assembly is required to be arranged on the filter in order to realize connection with external equipment to transmit signals. In addition, in order to stably transmit signals, an outer conductor surrounding the periphery of the connector assembly needs to be arranged on the cover plate of the filter, and a shielding elastic sheet can be arranged on the outer conductor and used for shielding the connector of the connector assembly. The outer conductor is in interference fit with the flange of the connector assembly through an elastic shielding member (such as a conductive rubber ring), and the elastic shielding member is compressed through the cooperation of the outer conductor, the elastic shielding member and the flange of the connector assembly, so as to realize the sealing between the connector assembly and the cavity.

In the creation process of implementing the technical scheme of the present application, the inventor finds that, due to the fact that the number of the assembly related parts of the connector assembly is large, the size change after assembly is large easily caused under the tolerance accumulation of the outer conductor, the elastic shielding member, the flange of the connector assembly, the cavity and the cover plate, the elastic shielding member may be in interference fit with the outer conductor to jack up the outer conductor, so that the outer conductor is loosened or even separated from the cover plate, and the shielding performance is affected.

Based on this, in order to solve the technical problem in the related art that the external conductor may be loosened after being interference-fitted with the flange of the connector assembly by the elastic shield to affect the shielding performance, the inventors have proposed the following solutions.

Referring to fig. 1 to 3, an embodiment of the present application provides a filter 100 for filtering a signal. The filter 100 may be a cavity filter, a duplexer, a splitter, a combiner, or a tower top amplifier, but is not limited thereto. The filter 100 comprises a cavity 10, a cover plate 20, an outer conductor 30, a connector assembly 40 and a resilient shield 50, wherein:

the interior of the chamber 10 may be provided with a signal transmission member, a filter element, and other elements necessary for the operation of the filter 100.

The cover plate 20 covers an opening of the chamber 10 to form a cavity with the chamber 10, for example, a resonant cavity may be formed. The cover plate 20 may be connected with the chamber 10 by screws or bolts.

The outer conductor 30 is disposed on the cap plate 20. The outer conductor 30 may be a ring structure or a cylinder structure, and has a hollow interior for the connector assembly 40 to pass through. The outer conductor 30 may be provided by a shield spring of the filter 100 to facilitate shielding at the interface of the connector assembly 40. The outer conductor 30 may be made of a metal material, but is not limited thereto, and other conductor materials may be used.

The connector assembly 40 is disposed through the outer conductor 30 and on the cavity 10. The connector assembly 40 serves as a carrier for transmitting signals of the filter 100 to an external device or transmitting signals of an external device to the filter 100. The connector assembly 40 may be any one of the prior art connector assemblies or a modified connector assembly from the prior art connector assembly.

Wherein the connector assembly 40 has a flange 411, the flange 411 being located between the cover plate 20 and the cavity 10. The elastic shield 50 is located between the cover plate 20 and the flange 411, and the elastic shield 50 abuts against the cover plate 20 and the flange 411. The cover plate 20 and the flange 411 sandwich the elastic shield 50, and the elastic shield 50 is elastically deformed to perform a sealing and shielding function. The elastic shielding member 50 refers to a structural member capable of being elastically deformed and performing a shielding function, such as a conductive rubber ring or a shielding rubber ring, but is not limited thereto.

The filter 100 provided by the embodiment of the application, by providing the cavity 10, the cover plate 20 covering the opening of the cavity 10, the outer conductor 30 disposed on the cover plate 20, and the connector assembly 40 penetrating through the outer conductor 30 and disposed on the cavity 10, and the connector assembly 40 having the flange 411 disposed between the cover plate 20 and the cavity 10, and by providing the elastic shielding member 50 disposed between the cover plate 20 and the flange 411 and abutting against the cover plate 20 and the flange 411, the cover plate 20 can press the elastic shielding member 50 to seal and shield between the flange 411 and the cover plate 20, thereby avoiding signal leakage inside the cavity 10, the outer conductor 30 does not need to abut against the elastic shielding member 50, and the elastic shielding member 50 can be prevented from pushing the outer conductor 30 due to the pressing of the outer conductor 30 to cause the looseness of the outer conductor 30, thereby effectively reducing the possibility of looseness of the outer conductor 30, and facilitating improvement of the stability of the outer conductor 30, thereby improving shielding performance. Moreover, since the elastic shielding element 50 is located between the cover plate 20 and the flange 411, and the cover plate 20 is stably disposed on the cavity 10, the elastic shielding element 50 can achieve a stable compression amount, which can improve the sealing and shielding effects between the cover plate 20 and the connector assembly 40, and further improve the reliability of the filter 100.

In one embodiment, referring to fig. 2, outer conductor 30 is not in direct contact with flexible shield 50. It can be understood that, since the outer conductor 30 is disposed on the cover plate 20 and the elastic shielding element 50 abuts against the cover plate 20, the outer conductor 30 and the elastic shielding element 50 are indirectly connected through the cover plate 20.

So set up, because outer conductor 30 and elastic shielding piece 50 are not direct contact, outer conductor 30 and elastic shielding piece 50 can not directly take place the interact of power, and elastic shielding piece 50 is compressed and the resilience force that produces when taking place elastic deformation can not direct action in outer conductor 30 promptly, can effectively avoid outer conductor 30 to receive elastic shielding piece 50's effort, further improves the stability that outer conductor 30 set up on apron 20.

Alternatively, in an embodiment, referring to fig. 2, the outer conductor 30 is located above the elastic shielding element 50, and a gap is formed between an end of the outer conductor 30 close to the cavity 10 and an end face of the elastic shielding element 50 close to the cover plate 20.

With such an arrangement, since the gap is formed between the outer conductor 30 and the elastic shielding member 50, the elastic shielding member 50 can be prevented from contacting the outer conductor 30 when being elastically deformed, and thus acting on the outer conductor 30, and the stability of the outer conductor 30 can be further improved.

It should be noted that, in other embodiments, the outer conductor 30 and the elastic shielding element 50 may also be in contact, that is, the outer conductor 30 may abut against the elastic shielding element 50, which is beneficial to improve the sealing and shielding effects. Alternatively, the force between the outer conductor 30 and the resilient shield 50 may be much less than the force required to be able to jack up the outer conductor 30; for example, the outer conductor 30 and the flexible shield 50 may just touch but the outer conductor 30 cannot elastically deform the flexible shield 50. Of course, in other embodiments, there may be some force between the outer conductor 30 and the resilient shield 50, but this force is not sufficient to jack the outer conductor 30.

In one embodiment, referring to fig. 2 and 3, the flange 411 is provided with a boss portion 412 adjacent to the end surface of the cover plate 20, and the boss portion 412 is located between the flange 411 and the cover plate 20. The boss 412 may be substantially annular, may be continuous, or may be discontinuous, and may be surrounded by a plurality of sub-protrusions. The outer diameter of the boss portion 412 is smaller than that of the flange 411, and the boss portion 412 and the flange 411 form a stepped structure. A seating space is formed between an outer side wall of the boss portion 412 and an end surface of the flange 411 adjacent to the cover plate 20, and the elastic shield 50 is located in the seating space.

So arranged, the mounting of the flexible shield 50 on the flange 411 is facilitated; moreover, the boss portion 412 can expand the elastic shielding element 50, so that the inner diameter of the elastic shielding element 50 is expanded to facilitate the outward movement of the elastic shielding element 50, thereby facilitating the contact with the cover plate 20, and increasing the contact area between the elastic shielding element 50 and the cover plate 20 without increasing the width of the elastic shielding element 50; the elastic shield 50 and the outer conductor 30 can adopt original sizes before improvement, and the elastic shield 50 does not need to be specially customized, so that the scheme of the embodiment of the application can be implemented under the condition of original parts, and the cost can be saved.

Alternatively, in one embodiment, referring to fig. 2 and 3, the boss portion 412 is provided with a first inclined structure 4120 at an end adjacent to the cover plate 20, and the first inclined structure 4120 is arranged to be inclined downward from the center line of the connector assembly 40 toward the edge of the connector assembly 40. The first inclined structure 4120 may be a tapered surface structure, or an inclined structure including a plurality of inclined surfaces, but is not limited thereto. It should be understood that the centerline of the connector assembly 40 is also the axis of the connector assembly 40.

With this arrangement, since the first inclined structure 4120 inclined downward from the center line of the connector assembly 40 toward the edge is provided at the end of the boss portion 412 close to the cover plate 20, when the elastic shielding member 50 is assembled on the flange 411, even if the elastic shielding member 50 is sleeved on the boss portion 412, the elastic shielding member 50 can slide into the installation space along the first inclined structure 4120 under the pushing action of the outer conductor 30, thereby preventing the elastic shielding member 50 from being erroneously mounted on the boss portion 412, and thus achieving the foolproof effect.

Alternatively, in one embodiment, referring to fig. 2 and 3, the end of the outer conductor 30 close to the first inclined structure 4120 is provided with a second inclined structure 311, and the second inclined structure 311 is inclined downwards from the center line of the outer conductor 30 to the edge of the outer conductor 30. The first inclined structure 4120 may be a tapered surface structure, or an inclined structure including a plurality of inclined surfaces, but is not limited thereto. It should be understood that the centerline of the outer conductor 30 is also the axis of the outer conductor 30.

With this arrangement, since the end of the outer conductor 30 close to the cavity 10 is provided with the second inclined structure 311 inclined downward from the center line of the outer conductor 30 toward the edge, the second inclined structure can cooperate with the first inclined structure 4120 to avoid the position of the outer conductor 30, so as to facilitate the assembly of the outer conductor 30. Also, the second inclined structure 311 is more favorable for pushing the elastic shielding member 50 so that the elastic shielding member 50 slides smoothly along the first inclined structure 4120 into the installation space.

Alternatively, the second inclined structure 311 is adapted to the first inclined structure 4120, i.e. the inclination trend of the second inclined structure 311 is substantially the same as the inclination trend of the first inclined structure 4120, it can also be understood that the second inclined structure 311 is disposed substantially parallel to the first inclined structure 4120, and the shapes of the two structures can be the same or similar.

Optionally, the second inclined structure 311 and the first inclined structure 4120 may have a gap therebetween to facilitate the assembly of the outer conductor 30. Of course, in other embodiments, the second inclined structure 311 may be adapted to the first inclined structure 4120, and the second inclined structure 311 and the first inclined structure 4120 may be in contact, so as to improve the sealing and shielding effects.

Of course, in other embodiments, the outer conductor 30 may not be provided with the second inclined structure 311, for example, the end surface of the outer conductor 30 close to the cavity 10 may be planar and higher than the first inclined structure 4120, and may not interfere with the first inclined structure 4120.

It should be noted that in other embodiments, the first inclined structure 4120 may not be provided on the boss portion 412. For example, the end surface of the boss portion 412 adjacent to the cover plate may be a flat surface.

It should be noted that in other embodiments, the flange 411 may not be provided with the boss portion 412 near the end surface of the cover plate 20. At this time, the elastic shield 50 may be directly placed on the flange 411, and since the effect of the boss portion 412 on the expansion of the elastic shield 50 is lost, the elastic shield 50 should have a certain inner diameter or width to be able to contact the cover plate 20.

In one embodiment, referring to fig. 2 and 3, the cover plate 20 is provided with a through hole 201. The outer wall of the outer conductor 30 is in interference fit with the inner wall of the through hole 201. Alternatively, the outer wall of the outer conductor 30 may be provided with a knurling structure (such as, but not limited to, cross-hatched knurling, straight-grained knurling, etc.), and the outer conductor 30 may be in interference fit with the inner wall of the through hole 201 through the knurling structure of the outer wall. Of course, the outer wall of the outer conductor 30 may be directly interference-fitted with the inner wall of the through hole 201 without providing a knurled structure.

This arrangement facilitates stable assembly of the outer conductor 30 to the cap plate 20.

It should be noted that the assembly manner between the outer conductor 30 and the cover plate 20 is not limited to this.

Alternatively, in other embodiments, the outer wall of the outer conductor 30 is threadably engaged with the inner wall of the through-hole 201. At this time, the outer wall of the outer conductor 30 is provided with male threads, and the inner wall of the through-hole 201 is provided with female threads.

In one embodiment, referring to fig. 1 to 3, the outer conductor 30 includes a first outer conductor portion 31 and a second outer conductor portion 32. The first outer conductor portion 31 is provided on the cap plate 20. Specifically, the first outer conductor portion 31 may be fitted to the cap plate 20 with an interference fit or a screw fit with the through hole 201, or fitted to the cap plate 20 with a fastener. The second outer conductor part 32 is sleeved on the first outer conductor part 31, and an inner wall of the second outer conductor part 32 is connected with an outer wall of the first outer conductor part 31. The connector assembly 40 is inserted through the first outer conductor portion 31 and the second outer conductor portion 32. It is understood that the first outer conductor portion 31 and the second outer conductor portion 32 may have a ring structure or a cylindrical structure, and have a hollow interior for the connector assembly 40 to pass through.

With this arrangement, the outer conductor 30 is configured to include the first outer conductor portion 31 and the second outer conductor portion 32, and can be assembled by being split and formed, for example, the first outer conductor portion 31 can be assembled on the cover plate 20 first, and then the second outer conductor portion 32 can be assembled on the first outer conductor portion 31, so that the outer conductor 30 can be prevented from being an integral structure and affecting the installation of screws or bolts on the cover plate due to an excessively large outer diameter.

Alternatively, referring to fig. 2, the inner wall of the second outer conductor part 32 and the outer wall of the first outer conductor part 31 may be in threaded engagement, where the outer wall of the first outer conductor part 31 is provided with an external thread and the inner wall of the second outer conductor part 32 is provided with an internal thread. Of course, in other embodiments, the inner wall of the second outer conductor part 32 and the outer wall of the first outer conductor part 31 may be in interference fit.

It should be noted that in other embodiments, the outer conductor 30 may be a unitary structure, i.e., a structural member.

Alternatively, in an embodiment, referring to fig. 1 to 3, the filter 100 includes a shielding elastic sheet 60, and the shielding elastic sheet 60 is disposed on the outer conductor 30. Specifically, the shielding elastic piece 60 is disposed on the second outer conductor part 32.

So set up, shielding shell fragment 60 can shield the interface of connector assembly 40 to do benefit to the stability that improves connector assembly 40 and carry out signal transmission.

The mounting hole 102 and the mounting groove 101 may be coaxially disposed. The outer wall of the connector assembly 40 is an interference fit with the inner wall of the mounting hole 102. Alternatively, the outer wall of the connector assembly 40 may be provided with a knurled structure (such as, but not limited to, cross-hatched knurling or straight-grained knurling), and the connector assembly 40 may be in interference fit with the inner wall of the mounting hole 102 through the knurled structure; of course, in other embodiments, the outer wall of the connector assembly 40 may be directly interference-fitted with the inner wall of the mounting hole 102 without providing a knurled structure.
